STEPHEN RYDER, OF NORTH ATTLEBOROUGH, MASSACHUSETTS, ASSIGNOR OFONE-HALF TO JOSEPH LEWIS BLAINE, OF SAME PLACE.

ELECTRICAL, CONNECTOR.

SPECIFICATION forming part of Letters Patent No. 292,180, dated January22, 1884.

1 Application filed November 2,1883. (No model.)

To all whom it may concern:

Be it known that I, STEPHEN RYDER, of North Attleborough, county ofBristol, and State of Massachusetts, have invented new'and usefulImprovements in Electrical Connectors; and I do hereby declare that thefollowing is a full and exact description of the same, reference beinghad to the accompanying drawings, and to the letters'of reference markedthereon.

This invention relates to that class of electrical devices which areemployed to connect the ends of different wires; and it consists incertain peculiarities of construction, fully described hereinafter, bymeans of which great simplicity is combined with perfect efficiency inobtaining the desired result.

In the drawings, Figure 1 represents a perspective view of myimprovedconnector; Fig. 2, a top view of the button; Fig. 3, a plan view of theconnector reversed, Fig. 4, a sectional view of the same; and Fig. 5, anenlarged view illustrating the relative position of the parts.

To enableothers skilled in the art to make my invention, I- will proceedto describe fully the construction of the same.

A, Fig. 1, represents a blocker base-piece of any proper material.

B represents a copper button havinga central opening, as shown in Fig.2, for the reception of a screw.

6, Figs. 3 and 4, represents a central portion of the button, which isdepressed to form an annular flange, as shown.

b, Figs; 3 and 4, represents a peripheral portion, which is bentdownward to form a rim or flange, as shown.

b b, Fig. 4, represent semicircular openings in the rim, by means ofwhich provision is made for properly receiving and holding the wires.

b b represent teeth projecting from the edge of the rim at properdistances apart, which are adapted to sink into the block, as shown inFigs. 1 and 4, for the purpose of fastening theconnector securely inplace.

0, Figs. 1, 3, and 5, represents the continuous wire, and c theauxiliary wire, which is to be connected therewith.

D represents the securing-screw. The position of the parts when theconnector is completed is shown in Figs. 1, 3, and 5.

The continuous wire, it will be observed, having a proper-portion of itslength exposed, is in direct contact with the'edge of the annular flangeb of the copper button B, as shown in Figs. 3 and 5, the flange itselfbeing firmly pressed upon it by the action of the securingscrew. Theauxiliary wire, it will be observed, having a proper portion of itslength exposed, is also in direct contact with the edge of this annularflange I), this flange also being firmly pressed upon it by the actionof the securing-screw. The 'parts in this position are firmly heldagainst disconnection. The button itself is firmly held by means of itsteeth, which are embedded in the base-block, and by means also of thesecuring-screw. The wires are securely held by the pressure of theannular flange b, and by the clamping action of the rim b. By means ofthis construction the wires are brought together in such manner that theelectrical connection is certain to be formed. The parts also are firmlysecured in their properrelative positions. The connector, also, in Viewof the efi'ectiveness of the result obtained, is very simple.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The copper button B, having the peripheral rim 6, with openings forthe wires and screw D in combination therewith, for moving it in adownward direction in such manner as to clamp the wires, as described.

2. The connector described, having the copper button with flange b, andrim b, having openings and teeth, in combination with a base-block andsecuring-screw, as described.

This specification signed and witnessed this 18th day of October, 1883.

STEPHEN RYDER.
